Meanwhile, the Syrian Observatory for Human Rights says U.S. airstrikes killed at least 30 people, including more than a dozen children, in Syria’s eastern province of Deir ez-Zor Monday. This comes after U.S. airstrikes on May 11 reportedly killed at least a dozen civilians, including eight children, north of the Syrian city of Raqqa. Two days earlier, airstrikes on two villages around Raqqa reportedly killed 19 civilians, including at least five children.
